From 91de344d7696ba8d7b92b7c503fdc0d3961e8cd2 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Sat, 25 May 2013 11:08:03 +0200 Subject: [PATCH] builtin_diff_tree(): make it obvious that function wants two entries Instead of accepting an array and using exactly two elements from the array, take two single (struct object_array_entry *) arguments.
